PAINTING DEVICE.

Specification of Letters Patent.

Patented June 7, 1921.

Application-med February 9, 1920. Serial No. 357,143.

To all whom t may concern:

Be it known that I, FRANKLIN E. FORN- wAL'r, a citizen of the UnitedStates, residing at Harrisburg, in the county of Dauphin and State ofPennsylvania, have invented new and useful Improvements in PaintingDevices, of which the following is a speciication.

My present invention pertains to painting apparatus and it contemplatesthe provision of a device whereby paint may be quickly and easilyapplied and this with a small amount of effort on the part of theoperator.

The invention further contemplates the provision of a device through themedium of which paint isl sprayed on to a surface in such manner thatthe work will present a. finished appearance and through the employmentof my novel device one person is enabled to accomplish as much as is nowaccomplished by approximately ten persons using the ordinary well knownpaint brush.

The invention in all of its details will be fully understood from thefollowing description and claims when the same are read in connectionwith the drawings accompanying and forming a part of this specification,in which:

Figure l is a side elevation of my novel paint applying device, and

Fig. 2 is a sectional view of Fig. 1.

Fig. 3, illustrates the peculiar nozzle used in my novel device.

Similar numerals of reference designate corresponding parts in theseveral views of the drawings. y

The pressure hose 1 of my device is connected to a paint reservoir (notshown) and said reservoir communicates with a compressed air tank notshown. The said hose 1 is threaded or otherwise secured to the tubularshaft or tube 2, and at its upper portion the tube 2 is provided with aseries of perforations 3 for an important purpose hereinafter set forth.

- the shaft 2 and is retained in proper position with respect to theshaft by the jam nuts l() and 11. Immediately above the forked portion 9I arrange the nut 12 that is threaded into the gland nut 13 asillustrated. In other words` it might be said that this constructioncomprises a nut within a nut. The nut 13 is exterior-ly threaded at 14and said exterior threads engage the bulletshaped casing 15. The saidnut 13 is provided with the portion 17 that confines the packing 16 inits proper place.

The nut 12 at its upper end is V-shaped to receive the packing 16.

Surrounding the upper end of the tube 2 and confined within the casing15 is a coil spring 18 that bears at its lower end on the portion 17 andits upper end on a pin 2O that passes through the upper yend of thehollow stem or tube 2. The tube 2 has a solld head 2l closing its endwhich is capable of being seated in the perforated upper end 22 of thecasing 15. l

As illustrated by Fig. 2 a tube or conduit 23 is threaded into theportion 22 of the casing and at its lower end the tube 23 communicateswith a head 24, as illustrated.

In the practical use of the device, the hose 1 is attached to a paintreservoir and paint is forced by compressed air or otherwise through thetube 2 and thence out of perforations 3 and by manipulation of thehandle 8 the velocity of the stream may be increased or decreasedaccording 4to the wish of the operator.

It will be seen by reference to the drawings that the gland nut 12 andnut '13 as well as the casing 15 are slidably movable with relation tothe tube 2 and that such relative movement is produced by manipulationof the handle 8 and hence the density of the flow of paint from thedevice is controlled by manipulation of said handle 8. My novel devicemay be moved up and down or to the right or left without diminishing theflow of paint, this being `a very advantageous feature because itpermits of the operation of the device by one erson.

My device is novel, from the act that, the casin or barrel revolves onthe tubular shaft, an .without any motion of the hand grasping thetricker or handle, by turning the barrel (and by means of the curvednozzle) the spray may be directed up and down or to the right or left atwill of the operator, without diminishing the flow of paint,

as there is but .one line of hose necessary to convey the fluld andforce to this device.

IThe operator by grasping the handle is enabled to control the spray andvary the force at the point of contact at will, which is an importantfeature of this device.

It will be gathered from the foregoing that my device when taken as awhole is compact and inexpensive to produce and comprises no delicateparts such as are likely to become inoperative after a short period ofuse.` Moreover, the device maybe readily cleaned with but a littleeffort and the advantages of this are apparent to those skilled in theart.

lHaving described my invention what I rclaim and desire to secure byLetters-Patent 1s l. In a painting apparatus the combination of a casinginteriorly threaded at its lower end, an outlet formed in its upper end,aconduit arranged in the outlet, a tube having orifices arranged thereinwithin casing y, and having a closed end adapted to close said outlet, anut threaded on the lower interior threads of the casing and secured toand movable with the casing, a gland nut secured to the first named nutand slidably arranged on the tube, jam-nuts on the tube spaced below thelast named nut, and a handle having a portion disposed between thejam-nuts and the gland nut for'movement of the gland nut, first namednut and casin relative to the tube.

2. n means for spraying paint and the like the combination of a casinghaving a discharge opening in its upper end, a tube arranged within saidcasing, a spring surrounding the tube, perforations formed in the tube,a seat surrounding said discharge opening, a solid head formed on theupper end of the tube for operating with said seat, a nut engaging thelower end ofthe casing and having a packing chamber surrounding saidtube, packing in said chamber and a second nut that engages and isconfined within the first-named nut and compresses said packing.

3. In a device for the purpose set forth, the combination of a tubehaving a closed upper end, a 'am nut surrounding the lower end of the tue, a second jam nut surround ing the tube and arranged above thefirstnamed nut, a handle mounted above the secondjam nut and alsosurrounding the tube,

vthat a a packin nut arranged on the tube above the hand e and slidablethereon, a nut surrounding said acking nut, packing interposed between te last named nuts, a spring surrounding the tube and bearing at itslower end on the uppermost nut that confines the packing, said tubehaving perforations formed therein, a pin arranged on the upper end ofthe tube, and a casing secured to said uppermost nut` and surroundingthe tube and having a discharge opening in its upper end, and a seatsurrounding said opening that receives the upper closed end of the tube.

4. In means for the purpose set forth, the combination of a casinghaving a discharge orifice at one endthereof, a tube ar ranged withinthe casing,'a spring arranged within the casing and surrounding the tubeand tending to move the tube toward said discharge orifice, aperturesformed inthe tube, a seat formed in the casing surrounding said orificea solid head formed on the tube for normally engaging said seat to closesaid orifice, a nut engaging the lower end of the casing and a secondnut that engages and is confined within the first-named nut; sald nutsbeing so constructed and arranged packing chamber is produced about thetube.

5. In a device for the purpose specified, the combination of a casinghaving a discharge opening at its upper end, a valve seat formed in thecasing and surrounding the opening, a tube confined within the caslngand having a solid upper end that normally rests in the valve seat ofthe casing to close the opening thereof, perforations formed in thetube, a nut secured to the lower end ofthe casing and surrounding thetube, a second nut resting in and secured to the first named nut, aspring surrounding the tube and abutting at its lower end and againstthe upper surface of the first-named nut, and a pin formed in the solidhead of the tube against which the upper end of the spring bears. i i

In testimony whereof I have hereuntolset my hand in witnesses. Y
